A sceptical voice arisen in the Software Engineering (SE) discipline, which is what Requirements Engineering (RE) is nested on, is that the SE must augment the approach towards reflecting human limitations and capabilities, which will require learning more about human errors and limitations in performing SE tasks and using the tools and products. RE tends to be studied in hard systems thinking, which is considered to be a lack of describing complicated real world problems. This thesis focuses on the extension of an interdisciplinary requirements elicitation framework towards business and IT (BIT) alignment. The interdisciplinary framework is developed by amalgamating two methodologies derived from different disciplines, namely goal-oriented RE from RE and Multiview from Information System (IS). IS usually considers human and social factors more than SE. Multiple perspectives concept (Technology (T), Organisation (0) and Personal (P) factors) in IS is enriched in analysis of human and social factors. The Multiview method grounded in soft systems thinking has adopted such multiple perspectives in IS development. RE and IS are found to be a core interdisciplinary concept that can be shared in order to produce the synergy of RE by adopting the approach that conceives social and human factors. IS development is targeted on BIT alignment, which is a Chief Information Officer's (CIO) primary concern. One of the strategic BIT alignment methods suggested by Henderson et al is to align IT with business strategy. However, business strategy driven RE is paucity. Therefore, the approach taken for this study is to drive business goal-oriented RE with multiple dimensions analysis of system environment, which is believed to be beneficial in a BIT alignment context in the RE process. There are several techniques and methodologies used for articulating the interdisciplinary requirements elicitation framework. The backbone of the framework is a simple goal tree that represents the business goals of a company. The goal tree is structured and decomposed by adopting multiple perspectives (Multiview). The Multiview is a driver in an expansion of the knowledge of firms' business goals since the multiple perspectives seize the diverse areas of concern in system development. Several modelling techniques are taken in order to specify and refine the requirements for each perspective. The contributions of the current study attempt: to reduce the gap between RE and IS in software requirements analysis (theoretical contribution); to be an opportunity to verify the applicability of the Multiview methodology in a requirements elicitation towards enhancing the strategic alignment of BIT (methodological contribution); and to develop a software tool to support the framework (practical contribution).
